LENS CLIP.

Application filed October 27, 19%, Serial No. 745,950.

My invention relates, to improvements in lens clips, that is,clips forfastening devices for holding the lens or front window of a headlight orfloodlight or other similar light casing in place. One object of myinvention is to provide a new and improved type of lens holder which maybe easily ap plied and which will remain tight under all conditionsAnother object is to provide a clip which will yieldingly hold the lensor panel in place under varying conditions of tei'nperature, expansionand the like. Other objects of my invention will appear from time totime in the course of the specification and claims.

My invention is illustrated more or less diagrammatically in theaccompanying drawings, wherein Figure 1 is a vertical section through adoor and lens;

Figure 2 is a plan view of one of the clips;

Figure 3 is a section along the line 3-3 of Figure 2 showing in dottedlines the clip in the compressed or working position.

Like parts are indicated by like characters throughout the specificationand drawings.

A is an annular ring or door adapted to be held in a headlight or otherlight casing by means not here shown. On the inner side of this ring ordoor is a groove A which may extend all the way around or may bediscontinuous as the case. may be. On the forward side is a flange Awhich overhangs clear around the inner periphery of the door. A is alens or glass panel flanged at A to engage a packing ring A which isslidaloly mounted in the ring A and abuts against the iiiverhanging sideof the flange A B is the lens clip. It has a downwardly bent tail Badapted to engage the groove or abutment A It is slotted at B toslidably engage a screw B threaded in the ring A and is downwardly andthen upwardly recurved at B so as to provide curved surfaces adapted oneof them to engage the inner periphery of the ring A and the other toengage the rear periphery of the packing rlng A When this clip isdropped into place the screw can be passed through the slot and thentightened up. This compresses the clip and causes it to press againstthe abutment A at one end and against the inner wall of the ring at theother. Further movement lengthens the clip causing it also to pressagainst thelens and liorce it forward against the overhanging flange AThis pressure somewhat upsets the clip and causes it to ex ert a springpressure against the lens. If the screw is screwed up far enough, thelens will be firmly though yieldingly seated in such manner thatvibration or expansion of the parts can. be compensated for by thespring action of the clip and the lens will be at; all times held inproper operating position.

It will be evident that while I have shown in my drawings an operativedevice, still manychanges might be made in the size, shape anddisposition of parts without (1eparting materially from the spirit of myinvention and I wish, therefor, that my showing might be taken as in alarge sense diagrammatic.

I claim:

1. A closure for lamp housings and the like comprising an annularinwardly flanged ring, a panel contained within the ring and adapted torest against the flange, an abutment on the opposed side of the ring anda plurality of holding elements adapted to be separately wedged betweenthe abutment and the panel, and means associated with the holdingelements for anchoring them in po sition and for adjusting the pressureexerted by them.

2. A closure for lamp housings and the like comprising an annularinwardly flanged ring, a panel contained within the ring and adapted torest against the flange, an abutment on the opposed side of the ring anda plurality of flexible holding elements adapted to be separately wedgedbetween the abutment and the panel and means associated with the holdingelements for anchoring them in position and for adjusting the pres sureexerted by them.

3. A closure for lamp housings and the like comprising an annularinwardly flanged ring, a panel contained within the ring and adapted torest against the flange, an abutment on the opposed side of the ring anda plurality of flexible holding elements adapted to be separately wedgedbetween the abutment and the panel, said holding elements comprisingclips adapted to engage the ring at one point removed from the panel andat another point adjacent the panel, and a screw threaded in the ringand adapted to compress the clip to slide that part which engages thering near the panel against and hold it in contact with the panel.

4. A closure for lamp housings and the like comprising an annularinwardly flanged ring, a shallow groove on the inner periphery thereofremoved from the flange having an aubutment surface opposed to theflange,

a plurality of spring clips each having a tail adapted to engage suchsurface and a hearing element adapted to engage the inner Wall of thering, a screw associated with each clip threaded in the ring, the clipbeing slotted where the screw passes through it, a panel containedwithin the ring adapted to engage the flange, the clip having a bearingsurface adapted to engage the panel and when the screw is tightenedforce the panel against the flange.
